论文摘要
我们报告了常规反射和马赫反射之间的过渡中滞后的机制。一个新的发现是，磁滞回路实际上是较高维路径的投影，即耗散表面的山谷线，其中最小值对应于稳定的反射配置。由于马鞍节点分叉表面的阀门，因此实际上是两个反射的过渡点。此外，预测的反射配置与实验和数值结果非常吻合，这是对该理论的验证。
We report the mechanism of the hysteresis in the transition between Regular and Mach reflections. A new discovery is that, the hysteresis loop is in fact the projection of a higher dimensional path, i.e. the valley lines in the surface of dissipation, of which minimal values correspond to stable reflection configurations. Since the saddle-nodes bifurcate the valleies of the surface, they are actually the transition points of the two reflections. Furthermore, the predicted reflection configurations agree well with the experimental and numerical results, which is a validation of this theory.
